T0 aZZ whom it may concern:

Be it known that I, THEODOR STEEN, en gineer, a citizen of the GermanEmpire, and a resident of the city of Berlin, Germany, have.

invented certain new and useful Improvements in Pipe-Couplings forDeep-Boring Apparatus, of which thefollowing is a speci-- fication.

The subject-matter of the present invengl tion relates to apipe-coupling for deep-boring apparatus in which the standards carryflushing-water pipes and'conveying or lifting apparatus for the slime.This pipe-coupling has for its object to connect, on the one Figure 1shows an entire view of the deep-- boring apparatus. Fig. 2 shows inelevation,

on an enlarged scale, only the upper portion thereof with thepipe-coupling in longitudinal section. 2, taken on the line A B. Fig. 4is a crosssection taken on the line C D.

The flushingwater pipe a serves as the standard for the apparatus andbranches on its lower end in a well-known manner, as shown in Fig. 1. ais closed, and the bolt 0, provided with a suspending-eye z or with ahook, may be screwed into or otherwise connected with the end of thepipe. Furthermore, the head or box I) is placed over the end of thepipeand rests upon the shoulder u of the said pipe at and is securedthereon through the medium of the nut 7c, screwed upon the bolt 0.

As will be seen from Figs. 2 and 4, the box I) is provided with twolongitudinal channels (1 and with one or more transverse channels e,which latter extend through the wall of the pipe 0.

At the lower end of the channels (2 is connected a flexible pipe or hoseg, provided with Fig. 3 is a cross-section of Fig.-

On its upper end the pipe a valve f and connected to the air-pipe h ofthe lifting device for the slime. In the pipe h is arranged in awell-known manner a conveyer lifting-pipe 1;.

It is obvious that the conveyer or liftingpipe '5 and the air-pipe 72.can be arranged adjacent to one another instead of one within the other,and, further, that one or more (two) lifting devices h '0' might beemployed without departing from the essence of the invention. Thelifting devices are connected with the flushing-water pipe through apipe-clamp m or thelike. On the head b a housing 11. is fitted, andwhich by the packings 1" bearing against the box 19 forms between thebox and the housing two chambers sand w. The chamber '3 forms a comm unication between the supplypipe w and the flushing-water pipe at,through the channel 6, while the chamber to forms a communicationbetween the compressed air 3 and the pipes 1 through the channel (1, sothat the flushing-water during the turning of the boring apparatus orwhile the housing 'n standsstill may flow from a; to a and thecompressed air in the pipes from y to g-that is to say, one can withoutinterrupting the introduction of flushing-water or air-pressurecontinually operate the boring apparatus, turning it about its axis andsimultaneously moving it up and down. Obviously one in this manner couldconnect the flushing-water pipe with the channel d and thecompressed-air pipe with the channel e, so that the flushingwater pipewill be fed from the chamber to and the compressed-air pipe of thelifting devices by the chamber 8.

Having thus described my invention, the

following is what I claim as new therein and 3. In a device of the classdescribed, the combination with the flushing-pipe, the lifting device,and a supply for each of them, of a coupling composed of two parts,movable relatively to, but having communication with each other, one ofwhich connects with the flushing-pipe and the lifting device, and theother of which connects with the flushingpipe supply and thelifting-device supply.

4. In a device of the class described, the combination with theflushing-pipe, a lifting device and a supply for each of them, of acoupling composed of two parts movable relatively to each other, one ofwhich is supported upon the flushing-pipe and is formed with alongitudinal channel which connects with thelifting device anda'transverse channel which connects with the flushing-pipe; and theother of which is formed with two chambers which form communicationsbetween the flushing pipe supply and the transverse channel, and thelifting-device supply and the longitudinal channel.

5. The combination with the pipe at having a shoulder u, and theflexible pipe g, of a head I) placed over the end of the pipe or,supported upon the shoulder u, and formed with a transverse channelwhich communicates with the pipe a and a longitudinal channel whichcommunicates with the pipe g, a bar 12 fitted upon the head b andadapted to rotate thereon, forming therewith two chambers, one of whichforms a communication between the transverse channel and asupplypipe,and the other of which forms a communication between the longitudinalchannel and another supply-pipe, substantially as described.

In testimony that I claim the foregoing as my invention I have signed mynamein presence of two subscribing witnesses.

THEODOR STEEN.
